The rise of nanometers

July 18th.

Three silicon steel synthesis cabins successfully arrived at the Guanghan Palace base.

The transport spacecraft unloaded three 28-ton silicon steel composite cabins. The transport spacecraft was parked not in the port area, but about 1.8 kilometers east of the scientific research area.

In fact, the current infrastructure in the port area is not perfect and needs to continue to be improved.

However, improving infrastructure requires a large amount of building materials. If the Golden Wing Dapeng + 11-meter-long lunar payload is calculated, it can only transport up to 94 tons of materials at a time.

For example, this time to transport three silicon steel composite capsules, a total of 84 tons of load was used, and 8.2 tons of related maintenance spare parts were stuffed into the three space capsules.

Next, there will be three aluminum alloy synthesis cabins, two material processing cabins, and a rare earth refining cabin. These space cabins will be pieced together to form the industrial area of ​​the Guanghan Palace Base, achieving self-sufficiency in most of the local infrastructure materials on the moon.

If local production of infrastructure materials is not achieved, even a 13-meter-long, more than 900-ton lunar payload assembled in low-Earth orbit will be a drop in the bucket.

For example, in the planning and construction of the port area, the initial plan is to build three spacecraft berths. The ground of each berth is required to be laid with foamed silicon steel, and then special nano-iron powder and nano-calcium powder are used to fill the pores of the foamed silicon steel.

Then a pure oxygen injection machine is used to react nano-iron powder and nano-calcium powder to generate ferroferric oxide and calcium oxide, and the foamed silicon steel is used as the skeleton to form the spacecraft berth.

The area of ​​each berth is a square with a side length of 1 kilometer, covering an area of ​​1 square kilometer. The floor thickness of the berth is required to be 0.5 meters, and 500,000 cubic meters of silicon foam steel need to be invested, weighing approximately 600,000 tons.

This is just a berth, plus tram tracks and other supporting facilities. In the preliminary planning of the entire port area, 3 million cubic meters of silicon foam steel will be consumed, and the weight is about 3.6 million tons.

Obviously this is an astonishing amount. If you add in the living areas, scientific research areas, industrial areas, etc. that will be expanded in the future, at least tens of millions of tons of silicon foam steel will be needed, as well as almost huge amounts of ferric oxide, calcium oxide, and oxidized steel. Silicon, aluminum alloy and the like.

Without the support of local industry on the moon, it is impossible to build a real lunar city.

Just when the Guanghan Palace base was busy installing the silicon steel synthesis cabin.

Southern Procellarum.

In the lunar sea, about 276 kilometers south of Kepler crater, the Noah Society's lunar base is located here.

A week ago, Haytham Hawke and Wade Clark, who successfully landed on the moon, were busy and anxious.

Noah's base on the moon will be called "Outpost 1". It currently weighs 75.4 tons and has six space capsules, three of which are living capsules and the remaining three are scientific research capsules.

NASA has successively deployed six related satellites in the moon's 150-1250 km orbit to assist Outpost 1.

Watching the window gradually dimming, Wade stopped what he was doing, put on a simple spacesuit inside the cabin, and returned to the living area. He wiped his face and the sticky areas on his body with a hot water wet cloth.

Hawke, who came back from another scientific research cabin, showed a tired smile: "Man, how are you doing today?"

"It's still the same. The efficiency of many chemical synthesis is lower than that of Blue Star. There may even be no reaction at all, or other compounds will be reacted." Wade spread his hands helplessly.

Obviously, NASA's scientific research department still chooses to follow the traditional chemical route in the synthesis technology of space materials.

Although there are many materials scientists in the international scientific community studying electric field synthesis, they have not formed a complete set of theories. Most of them are stuck on the synthesis of one or two compounds.

This kind of scattered situation naturally caused the electric field synthesis technology to be unpopular with NASA. Facing the urgent space race and severe internal economic problems, NASA did not dare to try it casually. After all, the current situation of electric field synthesis on the surface, The road ahead is still unclear.

The Noah Society, which pursues accelerating the construction of lunar colonies, will not allow a large amount of money to be invested in electric field synthesis. They can only improve traditional chemical synthesis little by little to adapt it to the lunar environment.

Through two communication relay satellites, the two contacted their families on the ground in the living cabin and sent several daily text messages.

As for surfing the Internet, it is possible, but it can only be accessed to designated websites, and the communication delay between the two parties is very large, and it takes more than ten seconds to go back and forth.

After dinner, Wade and Hawke, who were bored, turned on a few entertainment devices, an LCD TV, and flipped through some old DVDs.

Suddenly, an idea came to Wade's mind. He turned around and asked, "Hoke, can our two backup communication signal receivers be frequency modulated?"

"Of course, after all, there is strong electromagnetic interference in outer space, and we have to be careful of some man-made interference. It must be frequency modulated. Why do you ask this suddenly?" Hawke asked in confusion.

Wade whispered a few words in his ear. After listening to it, Hawke fell into deep thought and thought for a while: "You can try it, but do you know the other party's decoding program?"

"You can check it online."

The two of them took action, and soon they found many obvious satellite signals, and through the Internet, they found the decoding program of the Chinese satellite TV station. This program had already had several backups in the communication system of Sentinel 1.

Wade tried it again and found that one of the channels was a public satellite TV channel.

Connect the signal to the TV, then start the decoding program, and the picture will appear on the TV.

[Dear viewers in front of the TV, good morning, everyone, and welcome to Toad Palace TV...]

"It's true!" Hawke was very surprised.

Wade smiled and replied: "Man, they have more than 20 satellites on the moon. It is very normal to have satellite TV channels."

Suddenly Hawke asked an awkward question: "But, Wade, do you understand Chinese?"

"Uh..." Wade froze. Watching a TV show without a single English character, he felt a little frustrated.

Fortunately, the sky is the limit. Due to concerns about disputes between the lunar colonies and Greater China's lunar bases, in order to ensure timely communication, NASA has equipped the base with three sets of Chinese-English translation systems.

Wade took out a set of translators from the spare warehouse and plugged it into the TV. The sound of the TV program was immediately translated into English subtitles and English sounds.

It's just that the machine translation of English by the translator has some minor problems, and often incorrect translations occur.

However, the two of them were content at this time. They could at least make guesses. With the pictures, the general content could still be understood.

Toad Palace TV is a special TV station set up in the Toad Palace Space Station. The Toad Palace Space Station currently consists of 52 space capsules. One of the capsules is the dedicated capsule of Toad Palace TV Station.

The Toad Palace TV station has a host on the space station (an astronaut temporarily acts as a host). Currently, there are a total of 13 astronauts stationed in the entire Toad Palace space station, and the basic staffing is in place.

In addition, Toad Palace TV Station also owns three lunar orbit signal satellites, a Lagrange point signal satellite, and a Blue Star synchronous orbit signal satellite.

Through these satellites, satellite TV channels can be transmitted to the moon, synchronous orbit, low-Earth orbit, and blue star ground.

In fact, the Toad Palace TV station was not opened for a long time. It was only put into use at the end of April this year.
